noon-ornnerms MECHANISM.

Application filed July 31', 1916. Serial No. 112,279.

The present invention relates to improvements in door operatingmechanisms, and is particularly useful for motor vehicles andcarriages,in which the chaufieur or driver can by means of. myinvention, open and close the doors-of said vehicle without leaving hisseat. The device is useful and desirable in connection with taxi-cabs,as the chauffeur can. in inclement weather open and close the doors forhis passengers, without leaving his position at the steering wheel andoperating parts of the cab. 7

Another feature of my invention is that it can be used by making minorchanges in the present construction of automobiles, the usual locks onthe'doors being used with my invention. The parts of the invention whichoperate the spring tongue of the ordinary lock being located between theouter and inner side walls of the car body, as will be hereinafterexplained in this specification, and in a position which does notinterfere with the door itself, the slidable window sometimes used inthe door, can be used, same slidingdownward into and between theouterand inner walls of the door body as usual.

In the accompanying drawings forming part of this specification I haveillustrated one complete example of the physical embodiment of myinvention, constructed according to the best mode I have sofar de visedfor the practical application of. the is principles of the invention.Figure 1 is a vertical section through the vehicle body taken on line4-4 of Fig. .7

. Referring to the drawings the numeral 1 indicates'the body of avehicle, having'the usual outer and inner side walls 2, 3, and floor 4.,The door 5 has inner and outer walls 6, 7 and hinges 8, 9 attaching itto the vehicle body 1. 10 indicates a transverse a gear 22 whichmeshesinto the teeth on the under side of the arc plate 23. The arc plate23has a bearing at 24, supported by bent plate 25 attached to the underside of the floor at 26. A bent lever arm 27 is mounted on the uppermostend of the axle 28 forming part of the arc plate 23, but is free torotate thereon. The lever arm 27 has a downwardly disposed projection29, which passes through a slot 30 in the arc plate 23 for a purposedescribed below. The free end 31 of lever 27 is bent upwardlysubstantially at right angles, and is slidably attached to a rod 32, thelatter being mounted on the inner face of the outer partition 6 of thedoor 5, at points 33, 34. 35 shows the door 5 when thrown wide open bythe device.

Shaft 19 carries an adjustable disk 36,

shown in Figs. 4 and 6 in larger detail,

which has a depression 37, on the face oi the same, to receive thetongue 38, forming part of the bent end 39 of vertical lever 49.

rlln adjusting and locking screw 41 1s provided to look the loose disk,at any desired point on the shaft 19. Lover 40 1s i'ulcrumed at 42 in abracket 43, see I 9, attached to the wall 44 of the vehicle body 1.Lever 40 at its lower end operates against a spring 45 carried on a pin46, the latter being supported by a part 47, located. between the walls2, 3 of the vehicle body, so that lever 40 is always in contact with theface of disk 36, due to the constant pressure of the spring- 45.

shape, and bears at 48against a loose part or block of'l'cross-sectional shape, (see Fig. 3)", the latter being carried slidablyin a casing 50 attached by flanges 51 and 52 to the wall 44' beforementioned. T-blook 4.9 engages directly against the tongue 53 of theordinary lock 54 used in situations of this character on automobiledoors. The tongue 53 it will be noted protruding from the lock 54 isspring actuated from within the lock, and is normally in extendedposition and in engagement with casing 50, thereby holding the doorclosed with relation to the vehicle body 1. In this position of 53', thelever 40 occupies a substantially vertical position, due to the actionof the spring 45, tending to throw the lower end 55, and extension 38into Contact with the in dented portion 37, of disk 36, when the latter.is in proper position 011 shaft 19, and 36 is adjusted and set on saidshaft so that this is possible, and locked by 41 thereon".

The edge 56 of 38 is as shown in 5 rounded to present a smooth surfaceof as small frictional area as possible, whenin engagement with thedepression 37 of disk 36.

When disk 36 revolves it is seen that 38 will be thrown to the left asseen in Fig. 7, the upper end 48 of lever 40 thereby moving toward theright, as also part 49, and tongue 53 of the lo'clr54. In this fashion'53 is pressed back flush with 57 or the door and thereby allowing thelatter tobe opened when operated by lever 27 as'will be furtherexplained. y

If the tread 15 is now pressed forward to the left, see Fig. 8, thebevel gears 17, 18 operate, and shaft 19 will revolve as indicated byarrow Fig. 6, in which event disk 36 revolves, and allows door 5 to beopened as above described. its shaft 19 revolves, gear 22' operates arcplate 23', which last engages against projection 29 of lever 27, therebyrevolving 27 about central axle 28, and opening door 5 to position; 35upturned projection 31 sliding on 1*561132 during the operation". Thepurpose of the slot 30 in the are plate 23 is to provide a small amountIt is evident. that when thepart 13 is thrown backwardby using tread 16,as seen 111 Flg. 8 that: the reverse; operation will take place, and thedoor 5 will be retracted by lever 27, 53 engaging 50, thereby lookingthe door shut. In closing the door'the spring pressed tongue .53, as isusual has a rounded shape at 58 either concaveor convex, and asitengages against therside wall 44, it is readily depressed into.withdrawn position, and allows the doorto be fully closed by lever27.

It is to be noted further that the ordinary handle 59 of lock 54,showndottedin Fig. 7 can be used to open the door and. close same, whenit is desired to use it in the ordinary manner, without derangement ofany of the parts of this invention.

A hand lever 60 shown dotted in Fig: 7 can be used to operate the shaft10 as is readily seen, and thereby operate the .door insimi-lar'tfashion to that described above.

As the operating partsare practically attached only to the lower portionof the door 5, any window that may be in any particular type of vehicle,positioned slidably in the door, may still be used withoutalterationsofthe vehicle, andas for the most part the device isinclosedbetween the walls of the vehicle, and under the floor of same,it

can be applied to the ordinary type of automobile successfully, bymaking minor changes and additions tosaine: This advantage will bereadily appreciated.
